Subject: staging: comedi: adv_pci1710: remove boardinfo 'ai_maxdata'
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=853bbcc26368319cf0abafca88342a17b237c41c;p=linux-beck.git

staging: comedi: adv_pci1710: remove boardinfo 'ai_maxdata'

The analog input resolution is always 12-bits in this driver. Remove the
unnecessary boardinfo.
